Overview

There was lots of cloudy, rainy weather this month, but I still managed to image on 8 nights. There were two particularly notable variable star outbursts this month: V402 And (first since 2000 September) and QY Per (first since 1999 Dec 23-28).
The SXV-H9 is the imaging camera, with exposures for variable stars of 120 seconds at 4x4 binning (unguided). This month's session notes are below the overview section.

Session Notes

Thu/Fri October 2/3, 2005

I made a change to one line in AcquireSupport.wsc and reduced the "overhead" in my AcquireImages run by 40 minutes tonight. I think I know why this works, and the goal is to stay close to 90% time utilization on my all sky variable star runs.

QY Persei, 2005 October: 28/29 29/30
The gap in the middle of the Oct 29/30 light curve was caused by Windows switching the computer clock back from EDT to EST.
